Budget reversed intake manifold

[Thuppu]

Is it worth leaving standard hollow inside braces in the 3B manifold?

Like here on Thuppu's image:

My plenum is fully costom. Used only the 3B intake runners and flange. The braces are for avoid the big plenum to balloon and crack weldings on big boost levels. 2+bar makes quite a lot of force on big area walls.

Sure. I just used Your image to show the braces, which I mean. It might have been a little bit unfortunate case.

The 3B cut picture from motorgeek:



I just wonder if those braces are worthy on smaller manifold and on smaller boost, because I have seen lots of pictures of custom-made manifolds without those braces, and the builds looked pretty serious.

I cut them out of my ABY but mine was a pretty quick bodge job experiment to be fair.Haha.

the 3b ones are not braces but access holes to the flange bolts. they are hollow for long allen wrench not bracing

Thanks for that info BTW. It could be a fail.

Went to garage yesterday. Mocked-up 3B manifold with NM 20V cylinderhead and 3B cap. Did'n see any reason in keeping those access holes in the IM. Flange bolts would be relatively easily accessible.

Or I'm missing something?

Plenty of people have changed them without a long allen key, I removed mine without, its just a bit fiddlier/takes longer than with a long allen key through the plenum. Not that you really remove the intake manifold very often, hopefully.

[QUOTE=martinws;774685]My homemade reverse.
Had to make the 90degree elbow and moved PS pump to opposite side.

What did you make for the PS pump on the other side, do you have any pics?

I guess you would need to make up new PS pipes as the originals aren't very flexible and probably wont reach the other side of the engine.

Here are a few pics














I used a 3B alternator belt to fit this. I think i also used bits of an ABY AC bracket mated to the PAS pump and bracket from a B3 coupe, to be honest i just went through my box of bits and figured it out. I used a KV thermo housing and front hose to get more room, Im still running a typ85 radiator with no Aux rad. I had to get new lines made which were under £20 from hydraulics place down the road. Had to heat sleeve them as DP was too close for my liking.

My intercooler is right behind my front grill now as well so the pipework is only about 2ft now compared to at least 6ft with my old setup.

Just been thinking about reverse inlet again after PMing a member about mine.

Sitech Racing up in Scotland have a custom inlet for the focus RS That could be used with a custom adapter to fit our engines perhaps!







Just a thought.

In my opinion, the best solution is to move the alternator to the right side and leave the PS pump from the left, having moved it down. Or have them both on a stock AAN bracket.
Auto conditioning keeping makes the core problem.

Some slow progress of our amateur building btw:

Why did you use an NG engine inlet manifold?

[_ShurikeN]

Because I had one
And It's PS intake piece.

Actually I have plans to build a spacer for 2.2T throttle out of steel (I can do MIG welding myself). Or weld-on aluminium flange from 3B if I have access to free TIG welding further. It's expensive here unless I have a friend who can do it for me. It can last not forever.

Any new budget piece?
